PAPER CAN.

`SPECIFICATION forming part f Letters Patent N 0. 485,158, dated 0t0be125, 1892. Application filed December 15, 1891'. Sorial 110.415,112. (No model.)

To all whom it may concern:

YBe it known that L'ALPHoNsE "l. CWEnpI'NsKI, a citizen of the United States, residlng at Chicago, in-the county'of Cook and Stateof Illinois, have invented a certain new and useful Improyement in Paper Cans, (Gase `No. 1,) of which the following is a full, clear,

concise, and exact description, reference be` ing had to the accompanying drawings, formmg a part of this specification. n

.My invention relates to cans or boxes for holding articles of food, such as jelly, sirup,

and lard-in fact, anything-which it may be inside layer.- Parchment or waterproof paper has also sometimes been em ployd, this parchment-paper having been formed into the desired shape and placed within the outer portion of the box or casing, composed, usually, of

straw or Manila paper.

My invention is of special utility in the manufacture of cases designed to contain foods which are placed therein when hot or heated, 'which' would ooze through the paper when arranged as has been common heretofore. vThus where the. inside lining has been of paraine-paper the paraine, becoming melted, would rise yto the top of the heated contents,of the case. My invention consist-s more particularly in forming the cylindrical sides or portions of` the can out of a strip of paper wound upon itself and interposing between the layers' thereof, iirst, a winding of paraine-paper, and next andL preferably after the next convolution a layer of waterproof paper. 4In coninder.

nection' with this arrangement I preferably 5o employ a lining of parchment or Waterproof paper, this being desirable, for example, if the can or case is intended for holding substances which might be 'injuriously aiected by coming directly in contact with the straw or other paper forming the principal portion of the body of the can. As. many convolutions of the straw paper may be continued outside the outer layer of parchment-paper as may be'desired to give strength -to the cyl- The heads or ends of the case are preferably made slightly greater in diameterthan the diameter of the opening of the cylinder, and the 'inner edge of each of these heads being rounded off, these heads may be forced into the ends of the cylinder, and the paper expandingsomewhat tight joints will be formed. These heads I preferably coat with paraffine and lay a piece of paper over them, which will turn over the edges thereof a short distance. The outer portion of the edge of eachhead or end piece is brought directly in contact Y with the interior of the cylinder, and I preferably make the joint more secure by means.

of suitable cement or paste.

Myinvention will be more 4readily understod by reference to the accompanying drawings, in which- Figure'l is a central vertical-section oti a paper can or case embodying my invention, the lower Aend thereof being broken away. Fig. 2 is a horizontal' sectional view of the same.

Like parts are indicated bysimilar letters of reference throughout the different figures.

The cylindrical portion of the can is formed, as shown-most clearly in Fig. 2, of a piece a of strong cheap paper, as straw paper, wound upon itself in several convolutions a a2 a3 a",

&c. These convolutions constitute the main body or framework of the cylindrical portion of the case. The inner convolution. a', as shown in Fig. 2, is pasted or glued for a proper distance to` the convolution a2. The distance these twov convol'utions are directly in contactV may vary according to circumstances. I have found that if the two convolutions are cemented together furthe distance half the circumference of the' cylinder. I.

then interpose or interleave,so to speak, a

convolution b-of parai'ne-paper. The endsV b' b2 of this paraiine-paper preferably Voverlap orpass by one another,so as to breakv 1o joints on .opposite sid s the convolution a2, as

shown. Next in order I interleave the convolution c of parchment-paper, which is practically impervious to paraine, though the paraiine may be melted. Parchment-paper is also practically waterproof, though?, not in the sense or to the degree that paraine-pa-lv per is w'aterproof, for moisture will work through parchment-paper to a limited extent. The ends c c2 of the parchment-paper prefzo erably pass by one another to breakjoints,

as shown.

.As many additional lconvolutions of the main piece or body of the cylinder are added as may be desired to give the cylinder proper 2 5 strength.

y As shown in the drawings, I preferably provide an inner layer or convolution d of parch'- ment-paper to more securely protect the centents of the case fromI contact or commin- 3o gling in the slighest degree'with the parafue or any deleterious subst-ance that mightvby chance be present in the straw or other coarse paper,

f The manner ofcohstruc'ti'ng the heads cr" end pieces will vbe most readily understood by reference to Fig. 1. It will' be seen that the head e is made to fit the interior of the cylinder. The inner face e thereof 1 preferably coat with paraili ne. The paper disk f is pref- 4o erably of parchment paper and of only suflicient size'to allow the' edge f t0 1&9 over the rounded inner edge of the stopper or head e,

so that the outer portion of the edge of the.

stopper may come directly against and be cemented directly to the lining dor the inner portion of the cylinder, whatever it may be. The other head or end ofthe case may be constructed and secured in place the sameasdescribed with respect to the head e. Here- 5o toforeheavy paperorpasteboard hasbeen used for pails and cans or cases, as is shown in Letters Patent No. 140,148, granted Robert Mansure June 24, 1873; No. 156,694, granted- George H. Chinnock November 10, 1874, and- 5 5 N o. 336,963, grantedJames Tomlinson March 2, 1886. Inthe said Tomlinson patent ascrcll of weed is employed wound. upon'itself, and a strip of cloth or paper is inserted between the convolution's or turns. In the Chinnock 6o patentv a shell of wood or paper is v^`provided, between which an internal layer o-f-inodorous and tasteless paper and an intermediateair and water proof layer of shellac, parane, or equivalent is interposed. In vthe patent to Mansure the paper is cemented together and lined with tin-foil. Neither form of these il il lili ii'i,

iii

i iii priorcases or-pails would 'answer for pre- A servinglarticles o-f food which must be kept for a considerable period of time. I have attempted to use the forms shown in the'Mansure and the Chinnock patents, but without success, because the article of food, as frultpreserves, wouldwork through and become Ydamaged in ashort time. By completely sur- 'rounding the interleaved paraine-paper with lan; interleaved layer ofl parchment paper,

there being between the parchment-paper and n the, paraine one or more layers or turns of the gasteboard, I produce a case that 1s found enltirelysatisfactory. l My case as thus constructed is adapted y to receive articles of-food or anything 1t may be desired to put up innthisway while hot and in a liquid or plastic condition. The top or upper stopper being inserted and madetlght, t the contents will be secured against moisture and kept from evaporating for an indefinite period of time.' Myx paper can, thus constructed, is adapted 4for most of uses to which tin cans have been put heretofore and 1s g foundcheaper and much more convenient to o en. l

IHaving thus described my invention, I claim as new and desire to secure by Letters Patent- 4 g 1.
